[PATCH] [X86][SSE] Added support for SSE3 lane duplication shuffle instructions

That ping was a little premature! The movddup instruction was sometimes being pattern replaced with unpcklpd as the tablegen patterns hadn't been completed (there was a FIXME in X86InstrSSE.td) - I've updated the patch with a fix to the pattern and removed the FIXME.
